Oh, I see. This makes it harder for people to arena abuse though, which is a semi good thing you don't want the game to be too easy now would you? I would think you'd have to win the battle before you can move on to the next cameo/special character. What I always did in the GBA link arena is when I beat the game, I would choose my top 5 characters from that playthrough and they would start at the bottom of the "rankings" and they would have to fight their way up to the top against my other top 5 characters from other playthroughs and see which team was the best. This is exactly like the Paper Mario Thousand Year Door thing in Glitzville (if you played it). So if IS were to do this I'd say this should be in the Extras and you'd pick your best character(s) to fight off against stronger foes and a few cameo's here and there. You can get free weapons, stat boosts, items, but no exp. points because you can abuse it.
